RelayInterfaceSelector¶

simple module RelayInterfaceSelector

Selects the outgoing interface for the packet passing through from the MAC address table (forwarding information database) based on the destination MAC address. The selected interface is attached to the packet in an InterfaceReq. The packet may be duplicated if multiple interfaces are found.
